离子cordova构建ios –emulator不显示失败或成功构建

sudo ionic cordova build ios --emulator --prod

然后它开始正常构建,但构建似乎永远不会结束,因为这个过程永远不会返回“构建失败”或“构建成功”.它显然突然结束,这是终端的输出：

在此之前我的项目正在建设中.
我尝试使用该命令将目标更改为以前的iOS版本

离子cordova构建ios –emulator –target“iPhone-X,11.0”–prod

但它不起作用.在这个问题上最奇怪的事情是,如果我从Xcode构建应用程序,它“显然”采取我在appp中所做的更改.所以,这是我的离子信息：
